Their intelligence mainly results from their sensitive detection to the movement and static position of electric iron by using a special sensor. With the sensor, these chips can detect the vertical/horizontal position and movement status of IRON. These chips are equipped with on-chip shunt regulator, sensor signal processor, build-in oscillator, timer, logic control, power on reset and output driving block etc. Pin Assignment DISC/BUZ 1 RELAY 2 LED 3 GND 4 8 VCC 7 ACCLK 6 SW 5 TEST  Electric Iron Controller Fig1 PT8A351x pin assigment Pad Description Pin No. Pin Name I/O Description Discharge the external electrolytic cap to stabilize and limit its voltage.
